c. 5. BROWN CONCRETE WALL AND REENFORCING INSERT THEREFOR Filed Aug. 12. 1952 ATTORNEYS Patented Oct. 16, 1934 ATENT OFFICE CONCRETE WALL AND REENFOROING INSERT THEREFOR Charles S. Brown, Syracuse, N. Y.

Application August 12,

1 Claim.

This invention relates to a reeniorced concrete wall structure, particularly for pipes, bowls and the like, and the principal object of the invention is an insert for concrete walls of such shape that the inserts cannot lie flatwise alongside or crosswise of each other with extended surfaces in engagement and can only lie in any position with but small surfaces of the adjacent inserts tangent to each other, so that the inserts cannot wad or bunch together, and the concrete separates the inserts to a maximum extent at all points along the inserts, except at points where they may be tangent, or in other words, the invention consists of inserts which can touch each other only at small surface areas thereby providing a large space between the inserts for the concrete.

The invention consists in the combinations and constructions and novel features hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.

Figure 1 is a fragmentary view of a concrete wall embodying my insert.

Figure 2 is a detail view of the insert.

The insert comprises an elongated body having rounding heads at its ends, which are connected by'a small bar or shank, so that regardless of what relative positions the inserts take to each other, they can touch each other only at small areas.

1 designates the wall structure and 2 the reenforcing insert, each of which may be said to be in the general form of a dumb-bell having rounding heads 3 at its ends, which are connected by a shank or bar 4 arranged substantially coaxially with the heads.

In forming the wall, the inserts are mixed with the concrete in a concrete mixer and during the mixing operation are evenly distributed throughout the body of the concrete and owing to their shape, they can not lie close together regard- 1932, Serial No. 628,534

less of what relative angles they take to each other. The specific gravity of the inserts is nearly the same as that of the concrete, so that the inserts will not sink or float but will stay where they happen to be after the mixing operation. After being mixed, the concrete is poured into the desired form for pipes or conduits, bowls or other concrete wall structure. Owing to the fact that the concrete surrounds the inserts regardless of the angular positions they may take and to the fact that the inserts can touch each other only at small areas, only small areas on the surfaces of the Wall will be exposed in the finished wall, if at all, and the surface of the wall may be covered with suitable facing. The inserts may be made of any suitable material and are preferably metal, particularly a light metal, as aluminum. The inserts may be of any suitable size and for ordinary purposes are about one inch long. For thin walls, the inserts may be shorter and in some cases, as for small concrete bowls, vessels or pipes where the Wall is from one-half to one inch thick, may be about one-half inch long. In order to avoid having the inserts too heavy to mix readily in the concrete, the heads are discoidal with convex edges and outer surfaces, instead of spherical.

This insert is particularly advantageous for the reasons pointed out above, and also for the reason that it is economical to manufacture and reeniorces a concrete wall to a maximum without the use of wire fencing, etc.

What I claim is:

A. reenforced concrete wall structure having elongated inserts therein provided with rounding heads at its ends and a bar connecting the heads of less diameter than the heads, whereby the inserts, when mixed haphazard in the concrete, lie at various angles with only small surface portions thereof touching in any haphazard arrangement and the remainders thereof spaced comparatively wide distances apart.

CHARLES S. BROWN.
